Marvin is still a work in progress and still somewhat an experimental ‘prototype’, mostly due to instability in its components (ie., ever shifting Chrome Extension APIs). But should be functional enough to be of good service and help to Reddit aliens.

Current features:

If current URL has been posted to Reddit, display score, subreddit, author, etc.

If the URL has been posted multiple times to different subreddits, you can expand the ‘toolstrip’ by clicking the up-arrow icon to display the full information for all posts.

If it has not been posted, allows to post current page.

Voting.

Orange envelope notification, including number of new messages.

TODO:

Non-reddit.com domains support (post-1.0)

We need a favico-sized picture of Marvin for the toolbar!

More convenient re-post mechanism. (Done in 0.9.1)

Configuration interface and options:

Open comments and post pages in current or new tab?

Display tool-strip automatically if current URL has been posted. (This used to be the default behavior, but now has been changed to match Socialite.)

Install instructions

At the moment only the dev Chrome channel supports extensions and the extension packaging format is in flux, so if you want to try this, take precautions or you might be electrocuted.

The latest Marvin releases are only tested against the latest Chromium snapshots for Windows. (Feedback and bug reports are very welcome!) Note: Only the Chrome dev channel and the latest chromium releases support extensions and nothing else is likely to work. Note2: Chrome’s support for extension on Linux and OS X seems to be broken even more often than on Windows.

Download the .crx extension package for the latest Marvin from the Downloads page, and if you are running a modern enough version of Chrome you will be asked if you want to install the extension, say yes, and you are done!

If that doesn’t work you might need to start chrome as follows:

chrome.exe –enable-extensions –load-extension=‘c:\Documents and Settings[… path to the location where you have a copy of Marvin … ]\’

Usage instructions

Just click on the alien icon in the address bar to display information about the current page or submit the current page if it has not been submitted yet.

If you have any orange envelopes pending you will see the envelope and the number of pending messages in the toolstrip, click it to go to your inbox.

Known Issues

You need to visit reddit.com at least once per browsing-session before you can vote (if you haven’t, when you try to vote a new reddit.com tab will be open for you), this is needed to fetch the ‘modhash’ that the reddit API requires for voting. This issue should go away once we start to use the new auth mechanism for the JSON API, but it is still not clear how this should work.

If your vote causes the number of digits in the score to increase, the score display might become split and partially unreadable.

Chrome Extensions on Linux seem to still have many issues, the orange envelope notification works, but the address bar icon doesn’t, which makes the extension not very useful.

Code

Marvin’s blueprints are stored in a Mercurial repository, you can check out the code with the following command:

About the Sirius Cybernetics Corporation (SCC)

The Hitchhiker’s Guide to the Galaxy in a moment of reasoned lucidity, that is
almost unique among its five million nine hundred and seventy five thousand
five hundred and nine pages, says of the products of the Sirius Cybernetics
Corporation that “it is very easy to be blinded to the essential uselessness of
them by the sense of achievement you get from getting them to work at all”.

In other words, and this is the rock solid principle on which the corporation’s
galaxy wide success is founded, their fundamental design flaws are completely
hidden by their superficial design flaws, this not only suggests that the SCC
is responsible for the majority of personal computer Operating Systems sold
across the galaxy, it is a widely respected view, widely held by right
thinking people, who are largely recognizable as right thinking people by the
mere fact that they hold this view.
